Optimized Power Control, also known as Optimum Power Calibration, abbreviated OPC, is a function of
optical disc recorders.
It checks the proper writing power and reflection of the media in use, calculating the optimum
laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word ''laser'' originated as an acronym for light amplification by stimulated emission of radi ...
power and adjusting it for writing the particular session. More sophisticated is Active OPC or Running OPC. Active OPC monitors writing power and reflection of the media in use, calculating the optimum laser power and adjusting it in real-time, which, in theory, should result in a better quality
burn
A burn is an injury to skin, or other tissues, caused by heat, electricity, chemicals, friction, or ionizing radiation (such as sunburn, caused by ultraviolet radiation). Most burns are due to heat from hot fluids (called scalding), soli ...
